Estimating & BOQ 1 September 2026 6 min read

The floor planner is free for everyone, starting now

Draw or upload a plan, calibrate the scale, and get measured areas and a first-pass material take-off. No licence, no seat count, no trial clock. Here is what it does and what it deliberately does not.

Every estimate starts the same way. Someone opens a plan, measures rooms, writes areas on a printout, and types them into a spreadsheet. It takes a couple of hours, it is where a surprising number of costing errors are born, and it is the least interesting work in the whole business.

We built a tool for that hour. As of today it is free for everyone - no licence, no seat count, no trial clock, and no Nuvailo account required.

What it actually does

  1. 1

    Start from a drawing or from scratch

    Upload a plan as an image or PDF, or draw the layout directly on the canvas if all you have is a site sketch and a tape measure.

  2. 2

    Calibrate the scale once

    Click two points on a dimension you know - a 12 ft wall, a standard door - and type the real distance. Everything measured afterwards inherits that scale. This single step is what separates a real take-off from a guess.

  3. 3

    Trace the areas that matter

    Rooms, wet areas, external walls, the slab outline. Each closed shape carries its own area and perimeter.

  4. 4

    Read the first-pass quantities

    Areas, perimeters and counts, grouped so they line up with how a BOQ is actually structured rather than how a CAD file is.

Why free, and what the catch is

The honest answer: a take-off tool is only as useful as what happens next. If you are a Nuvailo customer, the quantities flow into a BOQ and then into the cost chain we have written about before. If you are not, you get the measurements and you take them wherever you like. We think enough people will want the second half that we do not need to charge for the first.

There is no data hostage clause. Export what you measure, close the tab, and never come back if it does not suit you. A tool you cannot leave is not a tool, it is a trap.

What it is not

This matters more than the feature list, because software oversold is software distrusted.

It isIt is not
A fast way to get measured areas off a planA drafting package - it will not replace AutoCAD or Revit
A first-pass quantity sheet you can sanity-checkA certified take-off you should submit without review
Accurate to the scale you calibrate againstAble to correct a distorted scan or a plan drawn out of scale
Useful for slabs, rooms, finishes, wet areasA structural quantity engine - rebar scheduling stays with your engineer
A take-off tool that claims to remove the quantity surveyor is selling you the one thing it cannot deliver. This one removes the tracing.

Where it fits in an estimate

  1. 1Measure the plan here. Minutes, not hours.
  2. 2Check the areas against your own spot measurements. Trust but verify, especially on the first few jobs.
  3. 3Price them - in Nuvailo against a BOQ template, or in whatever you use today.
  4. 4Keep the calibrated plan attached to the job, so the next person can see where a number came from.

Calibrate against the longest known dimension on the plan, not the shortest. A 2 percent error on a 1 metre reference becomes a 2 percent error on every wall in the building - measured over 10 metres, the same click precision costs you far less.

Questions this raises

Do I need a Nuvailo account to use it?+

No. The floor planner is open to anyone. An account only matters if you want the quantities to land in a BOQ and carry through to costing.

Will it stay free?+

Yes, for the take-off itself. We would rather earn money from the ERP than from the hour before it.

How accurate is it?+

As accurate as your scale calibration and your tracing. On a clean plan, calibrated against a long known dimension, it is good enough to price from. On a photographed printout at an angle, it is not - and no software fixes that.

Can I use it on a phone?+

It works, but tracing accurately with a finger is hard. Use a mouse or a stylus for anything you intend to price.
